7.3.6.2.1 JESD204B Frame Assembly in Bypass Mode

#GUID-827D8EC9-F03B-4205-9A09-1A715A08A6E9/T5752226-74 lists the available JESD204B formats and corresponding valid sampling rate ranges for the ADC34RF52. The sampling rates are limited by the minimum and maximum SERDES line rate as well as ADC sampling clock frequencies. The JESD204B frame assembly for the different lanes is shown in #GUID-827D8EC9-F03B-4205-9A09-1A715A08A6E9/T5752226-73.

(1) In full rate output, two LSBs are truncated to a 12-bit output.
(2) When using digital averaging the output resolution changes to 16-bit.
